Hot water systems in Murdoch
Across Murdoch, more households are rethinking their old gas and electric hot water system and switching to energy efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With an average household size of about 2.8 people and more than 4,200 occupied dwellings, steady hot water demand and rising energy costs make efficient hot water a smart upgrade. Many locals are established owner occupiers, with over 2,000 homes owned outright and another 1,290 with a mortgage, so improving comfort and cutting bills is a logical next step.
Murdoch’s sunshine is a big part of the story. The local weather station records mean daily solar exposure of around 19.2 MJ/m², which is roughly 5.3 kWh per square metre per day. That strong solar resource helps a solar hot water system or solar hot water heating system perform well, and also boosts the efficiency of a heat pump hot water system. When you combine that with the suburb’s solid median household income, many families can comfortably invest in an energy efficient hot water system that pays for itself through lower running costs and strong annual hot water energy savings.
In 6150, separate houses dominate, with plenty of three and four bedroom homes, so hot water demand per property is often high. That makes the choice of hot water system price / cost and long term efficiency important. Upgrading from an older gas unit or an ageing electric hot water system to the most efficient hot water system you can reasonably afford is one of the quickest ways to reduce energy use at home. Locally, brands like Rheem, Rinnai, Sanden and Thermann are common options, whether you are looking at a rheem solar hot water package, rheem heat pump hot water, rinnai solar hot water or a premium sanden heat pump for maximum efficiency.
Average annual bill savings in Murdoch will vary, but typical ranges look like this:
• Old electric to heat pump hot water installation: about $350–$700 per year • Gas storage to heat pump: about $250–$600 per year • Gas to solar hot water installation: about $200–$500 per year • Old electric to modern electric hot water installation with rooftop solar: about $200–$450 per year
These savings depend on your tariffs, hot water use and whether you also have solar power, but they give a sense of what is possible when you compare heat pump vs solar hot water or solar hot water vs electric hot water in real homes.

Hot Water Rebates, Tariffs & Savings
More Murdoch homeowners are now weighing up electric hot water vs gas hot water, and looking at options like the best heat pump hot water system, the best hot water system Australia can offer for their needs, or a straightforward solar hot water tank replacement. Federal incentives such as Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that gets taken off the purchase price. Western Australia schemes and retailer offers can sometimes add further hot water rebate wa support, especially for efficient electric hot water system rebate programs.
For many Murdoch homes, these discounts can reduce effective solar hot water price / cost or heat pump hot water price / cost by a substantial percentage, often bringing payback down to just a few years. When you combine rebates with self-consumption of your rooftop solar, use timers to run a heat pump during the day, or add solar-diversion controls, you can shave hundreds of dollars per year off bills and turn your system into a truly energy efficient hot water system.
